I am trying to add the DS1307 driver to my platform. I know the DS1307 is
present as I can run test code and read the registers. It's on the I2C-0
bus.
I have built the driver into the kernel and I can see the following in
dmesg output.
i2c-core: driver [rtc-ds1307] registered
but when the system boots further into the loading it displays the
following:
drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
I have tried to call the following code in *core.c* during the sun7i_init
call, which is called before the failed line above.
i2c_register_board_info(0, ds1307_i2c_board_info,
ARRAY_SIZE(ds1307_i2c_board_info));
with the following struct:
static struct i2c_board_info __initdata ds1307_i2c_board_info[] = {
{
.type = "rtc-ds1307",
.addr = 0x68,
},
};
but the ds1307 driver *probe* function never gets called.I read elsewhere
that I2C devices don't get probed as such so how do I get the probe
function to be called?
